    I purchased this to power my ONT whenever we have power outages and it's perfect for what i bought it for. I only have the Optical Network Terminal plugged into it and it powers it for well over qan hour with no issue. It's quite small and is easy to hide as well.

    I made this purchase looking for a battery back up that would not break the bank but would protect our periphals from surges which happens a lot here. The battery back up system came highly recommended and has good reviews. So far we are well please and have bought 3 more.

    I bought this to keep my internet and WiFi running with all these unannounced power outages, It kept everything running for 12 hours. It is a very compact unit that fits inside my wiring enclosure.

    Battery backup for modem and router

    I purchased this battery backup for use with my modem and mesh router. There was a lightning strike on my street earlier this year where I lost power and was out of town at the time. I could not communicate with items at home until I returned. The CyberPower unit was easy to set up and customize the alarm. Most important to me was the ability to replace the battery by myself in the future. With some other competitive brands, you needed to send the unit to the manufacturer for battery replacement.

    PART OF MY TOTAL POWER BACKUP SYSTEM

    Purchased this to bridge the gap when I have a power outage. My gas backup generator kicks in to power the house 15 seconds after a detected power outage. In the meantime, my computer will go offline without this unit. With the unit, my system stays up until my house generator kicks in so I have uninterupted power for my computer system. I also bought one for my modem and router to keep those online during the cutover in a power outage. This keeps my security cameras and video doorbell operating without interuption. There is a separate bank of surge protected outlets that I use for non-essential electronic accessories.

    This device really helps you if you have a nas or anything that needs to be charged so I recommend getting this it's not at a very bad price and you have surge protection for both signs and the battery backup again to charge anything you need at that moment if the power went out

    I really like this UPS. Good price for the security of not loosing power. It has a good number of plug-ins and it’s not too large it fit by my computer. I can fit all my components in this unit and it still has a few extra plugins.
